Since the extinction of dinosaurs, caused by the fall of an asteroid 66 million years ago, humanity wonders about the means of preventing such a disaster. Technological advances today make it possible to envisage solutions to protect our planet from these cosmic threats. Spatial agencies around the world, including NASA and China, are at the forefront of this struggle. They develop missions intended to divert or destroy asteroids likely to jeopardize life on earth.
China’s Dart 2.0 mission
Inspired by the success of the NASA Dart mission, China is preparing to launch its own asteroid deviation mission. This ambitious operation, nicknamed Dart 2.0, provides for the sending of a two -part spaceship: a section dedicated to observation and another designed for the impact. The ship would first be put into orbit around the targeted asteroid, allowing the observation section to collect precious data on its composition and its trajectory.
After an observation period of three to six months, the impactor part of the vessel would descend towards the asteroid to hit it with force. The objective is to modify its trajectory enough to divert it from the earth. This strategy, although risky, demonstrates the determination of China to protect our planet while affirming its technological know-how.

Asteroids, an underestimated threat?
Although the probability of a collision with a giant asteroid is low, the consequences would be catastrophic. Scientists therefore scrutinize the sky thanks to sophisticated telescopes such as Neo, which detect potentially dangerous celestial objects. Fortunately, current observations are reassuring: no asteroid of threatening size is planned to approach our planet in the near future.
Indeed, the pieces of rock which will approach the closest to us in the coming years will remain at a safety distance equivalent to a third of the Terre-Moon distance. This represents more than 100,000 kilometers, sufficient margin for us to sleep on our two ears. However, vigilance remains essential, because space is a dynamic and unpredictable environment.

Destruction of asteroids, between protection and competition
Efforts to destroy or deflect asteroids are not limited to a simple precautionary measure. They are also part of a context of international rivalry, where each nation seeks to demonstrate its technological power. China and the United States, in particular, are engaged in a new race for space, with ambitious objectives such as lunar exploration and manipulation of asteroids.
By developing technologies to destroy these cosmic threats, space agencies strengthen their position on the world chessboard. These daring missions are used not only to protect our planet, but also to establish the authority and reputation of the countries involved in space research. The destruction of asteroids thus becomes a strategic and symbolic quest, beyond its dimension of planetary security.

The future implications of these missions
Asteroid deviation missions open the way to new exciting perspectives. They could ultimately make it possible to explore and exploit the resources of these celestial objects, thus offering new economic opportunities. The rare metals and other precious materials present in asteroids could revolutionize our industry.
However, these projects also raise ethical and environmental issues. The handling of asteroids must be framed to avoid unforeseen consequences. In addition, international cooperation is essential to prevent possible geopolitical tensions. How can nations around the world collaborate to guarantee responsible and equitable use of these technological advances?
